v0.1.0 — first public release

First public release of gortk — a Go-native, zero-dependency LLM command-output compressor.

Highlights

• Lossless by default — unknown commands pass through untouched; loss is opt-in per filter and always recorded in Truncation.
• 94 filters imported from rtk's catalog (kept in sync via rtksync) plus hand-written extras and a structured go test filter.
• Credential redaction — masks cloud keys, tokens, JWTs, PEM keys, key=value secrets, and URL credentials; runs even on passthrough. Optional entropy scanning.
• Normalization — collapse UUIDs / timestamps / IPs / hashes to stable markers.
• Full-output recovery (Sink/FileSink), savings (Stats) and discovery (Discovery) observers, grouping stage, ultra-compact mode.
• Zero runtime dependencies (TOML import isolated in the rtkcompat module).

Measured ~47% byte reduction across the bundled fixtures (failure-preserving cases counted as 0%). See the README for the per-command table and how to measure your own.
